TECHNICAL FIELD

The disclosed embodiments generally relate to computerized systems andmethods for securing data, and more particularly, and withoutlimitation, computerized systems and methods that generate securedblock-chain-based ledger structures that facilitate event-based controlof tracked assets.

BACKGROUND

A block-chain is a distributed database incorporating a number of blockswhere each block contains data and/or programs and holds a valid“transaction” that is timestamped. As used herein, a “transaction” istypically a discrete operation that makes up, or is a part of, aninformation processing action. Each block in a block-chain also includesa link to a previous block in the block-chain thus creating a publicdistributed storage ledger, i.e., a log or an historical record, oftransactions. A robust distributed storage ledger structure (such as ablock-chain ledger structure) due to its public nature, redundantverification, and resistance to fraudulent activity, offers advantagesover existing centralized server systems. Despite its many advantages,conventional distributed storage ledger systems (such asblock-chain-based ledger systems) exhibit significant flaws, especiallywhen used to track assets in secure, high-risk, and/or sensitiveapplications.

Consistent with the disclosed embodiments, one or more of the componentsof computing environment 100 may be configured to address problemsinherent to conventional block-chain-based ledgers by embedding aprivate-master encryption key architecture into a conventionalblock-chain architecture (e.g., a block-chain-based architectureassociated with the public Bitcoin™ ledger). In some aspects, theresulting hybrid block-chain architecture may facilitate a selectiveencryption of information by client devices 102, 104, and 106, system140, and/or peer systems 160, thus providing a technical solution thatprotects sensitive and/or confidential instructions sets and eventtriggers and corresponding confidential instructions sets.

a. Exemplary Client Devices

In one embodiment, client devices 102, 104, and/or 106 may include acomputing device, such as, but not limited to, a hashing computer, apersonal computer, a laptop computer, a tablet computer, a notebookcomputer, a hand-held computer, a personal digital assistant, a portablenavigation device, a mobile phone, a smart phone, a wearable computingdevice (e.g., a smart watch, a wearable activity monitor, wearable smartjewelry, and glasses and other optical devices that include opticalhead-mounted displays (OHMDs), an embedded computing device (e.g., incommunication with a smart textile or electronic fabric), and any othertype of computing device that may be configured to store data andsoftware instructions, execute software instructions to performoperations, and/or display information on a display device(s),consistent with disclosed embodiments. In certain embodiments, at leastone of client devices 102, 104, and/or 106 may be associated with one ormore users, such as users 108, 110, and/or 112. For instance, user 110may operate client device 104 and may do so to cause client device 104to perform one or more operations consistent with the disclosedembodiments.

Client devices 102, 104, and/or 106 may include one or more tangible,non-transitory memories that store data and/or software instructions,and one or more processors configured to execute software instructions.Client devices 102, 104, and/or 106 may include one or more displaydevices that display information to a user and one or more inputdevice(s) to allow the user to input information to client device 102,104, and/or 106 (e.g., keypad, keyboard, touchscreen, voice activatedcontrol technologies, or any other type of known input device).

In one aspect, client devices 102, 104, and/or 106 may store in memoryone or more software applications that run on client device 104 and areexecuted by the one or more processors. In some instances, client device104 may store software applications that, when executed by one or moreprocessors, perform operations that establish communications with one ormore of peer systems 160 (e.g., across network 120) and that obtain,from peer systems 160, a current version of a hybrid block-chain ledgergenerated and maintained in accordance with the disclosed embodiments.

In other instances, and as described below, one or more of clientdevices 102, 104, and/or 106 may execute the one or more stored softwareapplication and to obtain data from the hybrid block-chain ledger thatincludes, but not limited to, data identifying one or more trackedassets, and/or a public key of one or more users. Further, and asdescribed below, the one or more executed software applications maycause client devices 102, 104, and/or 106 to extract, from the one ormore accessed blocks, a copy of an encrypted and/or hashedownership/rules portion of the transaction block (e.g., including theidentification a holder of a master key) and/or a copy of an encryptedand/or hashed master data block (e.g., encrypted using the master keyand including rules permitting preconfigured and/or actions involvingthe tracked assets). In additional instances, and as further describedbelow, client devices 102, 104, and/or 106 may provide informationassociated with one or more actions or transactions involving thetracked assets (e.g., information identifying the actions ortransaction, information identifying the assets, a public key, a digitalsignature, etc.) to peer systems 160, along with copies of the encryptedand/or hashed rules engines and lists of triggering events.

In some aspects, the one or more stored applications may include awallet application provided by business entity 150 (e.g., a mobilewallet application or an application executable on a desktop computer)and capable of initiating transactions denominated in one or morecurrencies, including virtual currencies such as Bitcoin™.

b. Exemplary Computer Systems

System 140 may be a computing system configured to execute softwareinstructions to perform one or more operations consistent with disclosedembodiments. In one aspect, system 140 may be associated with a businessentity 150 (e.g., a financial institution) that provides financialaccounts, financial services transactions, and investment services oneor more users (e.g., customers of the business entity 150). In someaspects, system 140 may be a distributed system that may includecomputing components distributed across one or more networks, such asnetwork 120, or other networks.

In one aspect, system 140 may include computing components configured tostore, maintain, and generate data and software instructions. Forexample, system 140 may include one or more servers (e.g., server 142)and tangible, non-transitory memory devices (e.g., data repository 144).Server 142 may include one or more computing devices that may beconfigured to execute software instructions to perform one or moreprocesses consistent with the disclosed embodiments. In one example,server 142 may be a computing device that executes software instructionsthat perform operations that provides information to one or more othercomponents of computing environment 100.

In one embodiment, server 142 may include a computer (e.g., a personalcomputer, network computer, or mainframe computer) having one or moreprocessors that may be selectively activated or reconfigured by acomputer program. In one aspect, server 142 (or other computingcomponents of system 140) may be configured to provide one or morewebsites, digital portals, etc., that provide services consistent withbusiness entity 150, such as a digital banking or investment portal, andservices consistent with disclosed embodiments. For instance, server 142may be configured to provide information associated with a requested webpage over communications network 120 to client device 104, which mayrender the received information and present content from the web page ona display device, e.g., a touchscreen display unit.

In other aspects, server 142 (or other computing components of system140) may be configured to provide information to one or more applicationprograms executed by client device 104 (e.g., through a correspondingapplication programming interface (API)). For example, client device 104may execute an application program associated with and provided bybusiness entity 150, such a mobile banking application and/or a mobilewallet application, to provide services consistent with the disclosedembodiments. In some instances, server 142 may provide information toclient devices 102, 104, and/or 106 (e.g., through the API associatedwith the executed application program), and client devices 102, 104,and/or 106 may be configured by the executed application program topresent portions of the information to corresponding users through acorresponding graphical user interface (GUI).

In further aspects, server 142 (or other computing components of system140) may be configured to provide to client devices 102, 104, and/or 106(and/or receive from client device 104) information associated withservices provided by business entity 150. For example, client device 104may receive the transmitted information, and store portions of theinformation in locally accessible storage device and/ornetwork-accessible storage devices and data repositories (e.g.,cloud-based storage). In one instance, client device 104 may executestored instructions (e.g., an application program, a web browser, amobile banking application, and/or a mobile wallet application) toprocess portions of the stored data and render portions of the storeddata for presentation to user 110. Additionally, server 142 may beincorporated as a corresponding node in a distributed network, andadditionally or alternatively, as a corresponding networked server in acloud-computing environment. Furthermore, server 142 may communicate vianetwork 120 with one or more additional servers (not shown), which mayfacilitate the distribution of processes for parallel execution by theadditional servers.

In further aspects, business entity 150 may represent a “controllingentity” capable of regulating transactions assets (e.g., units ofvirtual currency, units of various financial instruments, physicalassets, etc.) tracked within hybrid public-private ledgers consistentwith the disclosed embodiments. By way of example, one or more computingcomponents of system 140 (e.g., server 142) may be configured (e.g., byexecuted software instructions) to establish one or more rules thatregulate a distributions of and/or transactions associated with thetracked assets, an initiation of transfers of the tracked assets (e.g.,a sale, a use of the tracked assets as collateral in a securedtransaction etc.), and further, any additional or alternate actioninvolving the tracked assets and/or the hybrid public-private ledger(e.g., processes that generate additional cryptographic key sets foruser 110, processes that recover assets tracked in the hybridpublic-private ledger, etc.).

Additionally, in some aspects, system 140 may establish causalrelationships between one or more of the established rules and one ormore events that trigger an initiation of one or more correspondingregulated distributions, transfers, and/or other actions involvingassets tracked within the hybrid public-private ledger (e.g.,“triggering events”). For example, a confirmed loss of a privatecryptographic key issued to user 110 may represent a triggering eventthat causes system 140 to verify user 110's identity, initiate atransaction of the orphaned assets, generate a new pair of public andprivate cryptographic keys for user 110 (i.e., public and privateblock-chain keys), and transmit at least the private block-chain key touser 110 through secure, non-accessible processes, in accordance withone or more of the established rules.

Further, by way of example, a theft of a portion of user 110's trackedassets (e.g., units of virtual currency specified within one of moreblocks of the hybrid public-private ledger) may represent a triggeringevent that causes system 140 to initiate a recovery protocol to generatea transaction request to recover the value of the stolen assets (e.g.,to transfer the stolen assets back to user 110), and further, togenerate a new pair of public and private block-chain keys for user 110,as described above. In other instances, a death and/or incapacitation ofuser 110 may represent a triggering event that causes system 140 toinitiate a series of transaction to distribute of at least a portion ofthe tracked assets (e.g., through corresponding transaction requestsconsistent with the disclosed embodiments) to one or more additionalowners identified by user 110 and specified within corresponding ones ofthe identified rules.

In some aspects, system 140 may be configured to establish one or moreof the rules, and further, one or more of the causal relationships andtriggering events, based on internal regulations associated withbusiness entity 150. For example, the one or more internal regulationsassociated with business entity 150 may specify that system 140 verifyan identity of user 110 (e.g., based on various forms of multi-factorauthentication data) and/or obtain specific elements of documentation(e.g., a police report, etc.) prior to initiating the lost private keyprotocol and/or the recovery protocols outlined above. In other aspects,system 140 may one or more of the rules and/or triggering events basedon information received from user 110 (e.g., as input provided to a webpage or other graphical user interface (GUI) presented by client device104 and provided to system 140). For example, user 110 may specify, asinput to the web page or GUI presented by client device 104, one or moreindividuals that would receive portions of the tracked assets uponcompletion of one or more tasks and/or in the event of user 110'saccidental death. The disclosed embodiments are, however, not limited tothe exemplary triggering events and established rules described above,and in further aspects, the disclosed embodiments may be configured togenerate any additional or alternate user- and system-specified rulesand triggering events consistent with the hybrid public-private ledgerand appropriate to the tracked assets, user 110, and/or business entity150 (i.e., acting as a centralized authority for the hybridpublic-private ledger).

Further, and as outlined below, system 140 may be configured to storethe one or more established rules (e.g., as a rules engine) and one ormore of the established trigger events (e.g., as an event trigger list)within a portion of a local data repository (e.g., data repository 144).Additionally or alternatively, system 140 may be configured to storeportions of the rules engine and/or event trigger list within a securedata repository accessible to system 140 across network 140 (e.g.,cloud-based storage).

As described above, one or more computing components of system 140(e.g., server 142) may be configured to generate pairs of public andprivate block-chain keys for user 110 (e.g., user 110's public/privateblock-chain key pair), and to provide the generated private block-chainkey to user 110 through secure, non-accessible and/or out-of-bandcommunications (e.g., by mail, etc.). In further embodiments, the one ormore components of system 140 (e.g., server 142) may be configured togenerate and maintain additional cryptographic keys that facilitate ageneration and maintenance of portions of the hybrid public-privateledger. For instance, system 140 may be configured to generate a masterkey, which system 140 may leverage to encrypt the stored rules engine.In certain aspects, system 140 may store copies of the generated masterkey in a portion of data repository 144 that is not accessible to user110 (and any other users), thus maintaining a confidence of thegenerated master key.

In additional aspects, system 140 may be configured to generate andmaintain a private crypto key on behalf of user 110 (and additionally oralternatively, user 108 and 112), which system 140 may leverage toencrypt the stored event trigger list, and which may be provided to user110 (and/or to user 108 and 112) through secure, non-accessible and/orout-of-band communications. Further, and as described above, system 140may store copies of the private crypto keys in a portion of datarepository 144.

Further, in additional embodiments, one or more computing components ofsystem 140 (e.g., server 140) may be configured to hash the generated(and encrypted) rules engine and event trigger list into a genesis blockassociated with the hybrid public-private ledger. In other aspects,system 140 may provide the encrypted rules engine and event triggerslist to one or more of peer system 160, which may be configured to hashthe encrypted rules engine and event trigger list into the genesisblock. By way of example, and by hashing the encrypted rules engine andevent trigger list into the genesis block of the hybrid public-privateledger, the disclosed embodiments enable an in-band communication of theencrypted rules engine and event triggers from user to user withinblocks (e.g., transactions) of the hybrid public-private ledger

c. Exemplary Data Repositories and Stored Data

Data repository 144 may include one or more memories that are configuredto store and provide access to data and/or software instructions. Suchmemories may include tangible non-transitory computer-readable mediathat store software instructions that, when executed by one or moreprocessors (e.g., of server 132), perform one or more operationsconsistent with disclosed embodiments. Data repository 144 may also beconfigured to store information relating to business entity 150, e.g., afinancial institution.

For instance, data repository 144 may store customer data that uniquelyidentifies customers of a financial institution associated with system140. By way of example, a customer of the financial institution (e.g.,users 108, 110, and/or 112) may access a web page associated with system140 (e.g., through a web server executed by a corresponding front end),and may register for digital banking services and provide data, whichmay be linked to corresponding ones of users 108, 110, and/or 112, andstored as customer data within data repository 144. The stored customerdata may, for example, include personal information, government-issuedidentifiers, employment information, and contact information. The storedcustomer data may also include authentication credentials associatedwith registered users of the financial institution (e.g., a user name, auser-specified password, a system-generated password, an alphanumericidentification number (e.g., a PIN number) specified by the users orassigned by financial system 140, biometric information, and informationfacilitating enhanced authentication techniques).

In additional aspects, and as described above, data repository 144 maystore a rules engine identifying or more rules that regulate adistribution of the tracked assets, an initiation of one or moretransactions involving the tracked assets (e.g., a sale, a transfer inownership, a use of the tracked assets as collateral in a securedtransaction etc.), and further, any additional or alternate actioninvolving the tracked assets and/or the hybrid public-private ledger(e.g., processes that generate additional cryptographic key sets forusers 108, 110, and/or 112, processes that recover assets racked in thehybrid public-private ledger, etc.). Further, and as described above,data repository 144 may also store information identifying an eventtriggers list that identifies causal relationships established by system140 between one or more of the established rules and one or more eventsthat trigger an initiation of one or more corresponding regulateddistributions, transactions, and/or assets tracked within the hybridblock-chain ledger (e.g., “triggering events”).

In some aspects, system 140 may be configured to establish one or moreof the rules, and further, one or more of the causal relationships andtriggering events, based on one or more internal regulations associatedwith business entity 150. In other aspects, system 140 may one or moreof the rules and/or triggering events based on information received fromone or more of users 108, 110, and/or 112 (e.g., as input provided to aweb page or other graphical user interface (GUI) presented by clientdevices 102, 104, and/or 106 and provided to system 140).

In an embodiment, data repository 144 may also store a copy of a masterkey and private crypto keys associated with users 108, 110, and 112 (andadditionally or alternatively, additional private crypto keys associatedwith other users). By way of example, system 140 may be configured tostore the private crypto keys in a data structure that includesinformation that associates the private crypto keys with correspondingones of user 108, 110, and 112, and further, may be configured to storethe master key in a data structure within data repository 144 that isinaccessible to users 108, 110, and/or 112 (and additionally oralternatively, to other users). Further, in some aspects, datarepository 144 may be configured to store the rules engine and/or eventtriggers list in raw, unencrypted form. In other aspects, consistentwith the disclosed embodiments, data repository 144 may be configured tostore the rules engine and/or event triggers in encrypted form (e.g.,using the stored master key), and/or store a hashed representation ofthe rules engine and/or the event triggers list.

d. Exemplary Communications Networks

Communications network 120 may include one or more communicationnetworks or medium of digital data communication. Examples ofcommunication network 120 include a local area network (“LAN”), awireless LAN, a RF network, a Near Field Communication (NFC) network,(e.g., a “WiFi” network), a wireless Metropolitan Area Network (MAN)connecting multiple wireless LANs, NFC communication link(s), and a widearea network (“WAN”), e.g., the Internet. Consistent with embodiments ofthe present disclosure, communications network 120 may include theInternet and any publicly accessible network or networks interconnectedvia one or more communication protocols, including, but not limited to,hypertext transfer protocol (HTTP) and transmission controlprotocol/internet protocol (TCP/IP). Communications protocols consistentwith the disclosed embodiments also include protocols facilitating datatransfer using radio frequency identification (RFID) communicationsand/or NFC. Moreover, communications network 120 may also include one ormore mobile device networks, such as a GSM network or a PCS network,allowing client device 104 to send and receive data via applicablecommunications protocols, including those described herein.

e. Exemplary Peer Systems

Referring back to FIG. 1, peer systems 160 may include one or morecomputing systems configured to execute software instructions to performone or more operations consistent with disclosed embodiments. In someaspects, peer systems 160 may include computing components configured tostore, maintain, and generate data and software instructions. Forexample, each of peer systems 160 may include one or more computingdevices (e.g., a server, network computer, or mainframe computer) havingone or more processors that may be selectively activated or reconfiguredby executable instructions (e.g., computer programs) stored in one ormore tangible, non-transitory computer-readable storage devices.

In an embodiment, one or more of peer system 160 may be configured toreceive, from client device 104 across network 120, informationassociated with a distribution of, transaction involving, or otheraction associated with one or more assets tracked within hybridblock-chain ledgers consistent with the disclosed embodiments. By way ofexample, the received information may include, but is not limited to,data identifying at least a portion of the tracked assets, dataidentifying a current owner of the portion of the tracked assets (e.g.,user 110) (or a obfuscated owner identifier), and further, encryptedcopies of and/or hash values representative of the rules engine andevent triggers list.

In some aspects, the one or more of peer systems 160 may be configured(e.g., by the executed software programs) to validate the receivedinformation and to generate a new block of the hybrid block-chain ledgerthat includes the received information, either alone (e.g., using a “onetransaction, one block” paradigm) or in combination with informationidentifying additional distributions, transactions, or other actionsassociated with one or more tracked assets (e.g., as amultiple-transaction block). The one or more of peer systems 160 may befurther configured to generate one or more hashes representative of thenew block, which may be appended to a prior version of the hybridprivate-public ledger along with the newly generated block. In someaspects, the one or more of peer system 160 may maintain the updatedversions of the hybrid private-public ledger (i.e., the latest, longesthybrid private-public ledger), and may provide the updated version ofthe hybrid private-public ledger to client devices 102, 104, and/or 106(and additionally or alternatively, other client devices associated withother users) upon receipt of a request across network 120 and/or atregular or predetermined intervals. In some aspects, one or more of peersystems 140.

In certain instances, and in addition to a connection with network 120,peer systems 160 may be interconnected across a peer-to-peer network(not depicted in FIG. 1) using any of the wired or wirelesscommunications protocols outlined above. Further, in some instances, oneor more of peer systems 160 may function as a “miner,” where any minermay be compensated in units of a virtual currency (e.g., Bitcoin™) forvalidating the received data and for generating updated versions of thehybrid block-chain ledger.

II. Exemplary Processes for Tracking Assets Using Hybrid Private-PublicLedgers

In some embodiments, client devices 102, 104, and/or 106 may execute oneor more stored applications that enable corresponding users to track, inconjunction with peer systems 150 and other components of computingenvironment 100, a disposition and distribution of one or more assetsusing conventional, publicly available and transparent block-chainledgers. In some aspects, the use of public block-chain ledgers to trackownership, disposition, and distribution of actual and/or virtual assets(e.g., unit of virtual currencies, such as Bitcoin™, unit of otherfinancial instruments and securities, physical assets, etc.) may presentadvantages over existing centralized server systems, such as thoseprovided by financial institutions that leverage private ledgers.

a. Asset Tracking Using Conventional Block-Chain Ledgers

FIG. 2 is a schematic diagram of an exemplary structure 200 of aconventional block-chain ledger, which may be generated through theinteraction of components of computing environment 100. For example, asdescribed in reference to FIG. 2, a user (e.g., user 110) may beassociated with a device (e.g., client device 104) that executes astored software application (e.g., a wallet application) capable ofobtaining a current version of a conventional block-chain ledger fromone or more networked computer systems (e.g., one of peer systems 160configured to “mine” broadcasted transaction data and update ledgers).In some aspects, the current version of a conventional block-chainledger may represent a “longest” block-chain ledger than includes amaximum number of discrete “blocks,” which may identify transactionsthat transfer, distribute, etc., portions of tracked assets amongvarious owners, including user 110.

For example, client device 104 may obtain the current block-chainledger, and may process the block chain ledger to determine that a priorowner (e.g., user 108) transferred ownership of a portion of the trackedassets to user 110 in a corresponding transaction (e.g., transaction202, schematically illustrated in FIG. 2). As described above, one ormore of peer systems 160 may have previously data verified, processed,and packed associated with transaction 202 may be into a correspondingblock of the conventional block-chain using any of the exemplarytechniques described above and/or apparent to one of ordinary skill inthe art.

In some aspects, as illustrated in FIG. 2, transaction 202 may includeinput data that references one or more prior transactions (e.g.,transactions that transferred ownership of the tracked asset portion touser 108), and further, output data that includes instructions fortransferring the tracked asset portion to one or more additional owners(e.g., user 110). For example, input data consistent with the disclosedembodiments may include, but is not limited to, a cryptographic hash ofthe one or more prior transactions (e.g., hash 202A) and the set ofrules and triggers associated with the assets while the output dataconsistent with the disclosed embodiments may include, but is notlimited to, a quantity or number of units of the tracked asset portionthat are subject to transfer in transaction 202 and a public key of therecipient (e.g., public key 202B of user 110).

Further, in some aspects, the transaction data may include a digitalsignature 202C of user 108 (e.g., the prior owner), which may be appliedto hash 202A and public key 202B using a private key 202D of user 108through any of a number of techniques apparent to one of skill in theart and appropriate to the conventional block-chain ledger architecture.By way of example, the presence of user 108's public key withintransaction data included within the conventional block-chain ledger mayenable client device 104 and/or peer systems 160 to verify user 108'sdigital signature, as applied to data associated with transaction 202.

In an embodiment, user 110 may elect to further transfer the trackedasset portion to an additional user (e.g., user 112). For example, asdescribed above, client device 104 may execute one or more softwareapplications (e.g., wallet applications) that generate input and outputdata specifying a transaction (e.g., transaction 204 of FIG. 2) thattransfers ownership of the tracked asset portion from user 110 to user112, and further, that transmit the generated data to one or more ofpeer systems 160 for verification, processing (e.g., additionalcryptographic hashing) and inclusion into a new block of the clock-chainledger.

For example, data specifying transaction 204 may include, but is notlimited to, a cryptographic hash 204A of prior transaction 202, aquantity or number of units of the tracked asset portion that aresubject to transfer in transaction 204, and a public key of therecipient (e.g., public key 204B of user 112). Further, in some aspects,the data specifying transaction 204 may include a digital signature 204Cof the user 110, which may be applied to hash 204A and public key 204Busing a private key 204D of user 110 using any of the exemplarytechniques described above. Further, and by way of example, the presenceof user 110's public key 202B within transaction data included withinthe conventional block-chain ledger may enable various devices andsystems (e.g., client devices 106, 106, and/or 108, peer systems 160,etc.) to verify user 110's digital signature 204C, as applied to dataspecifying transaction 204.

As described above, one or more of peer systems 160 may receive the dataspecifying transaction 204 from client device 104. In certain instances,peer systems 160 may act as “miners” for the block-chain ledger, and maycompetitively process the received transaction data (either alone or inconjunction with other data) to generate additional blocks of theledger, which may be appended to the block-chain ledger and distributedacross peer systems 160 (e.g., through a peer-to-peer network) and toother connected devices of environment 100.

In some aspects, conventional block-chain ledger architectures describedabove may enable the public to review content of the ledgers and verifyownerships. Further, the decentralized nature of conventionalblock-chain ledgers may also enable multiple distributed networks toverify the contents of a single ledger. The resulting redundancy mayrender conventional block-chain ledger architecture more robust thancentralized server systems, and effectively eliminate the falsificationof ledger data by malicious parties.

Despite these advantages, conventional block-chain ledger architecturesmay exhibit significant flaws when implemented by secured, high-risksystems. By way of example, unencrypted conventional ledger blocks mayrepresent a security concern for transactions of sensitive nature, andfurther, may represent a privacy concern for members of the generalpublic. For instance, information indicative of an interaction of aprior asset owner and a corresponding device, as present withinconventional block-chain ledgers, may represent private information thatshould not be available to future owners, let alone members of thepublic.

Further, if an owner were to lose or misplace a corresponding privatekey, the distributed nature of conventional block-chain ledgerarchitectures, such as those described above, provide little recourse torecover possession of the one or more tracked assets. In certainaspects, the rigidity and inflexibility of these conventionalblock-chain ledger architectures, and their inability to adapt tochanging circumstances (e.g., loss of private keys, theft of trackedassets due to fraudulent or malicious activity), often results involatility in the usage of the tracked assets and an erosion in a publictrust of conventional block-chain ledgers.

Thus, there is a need for improved systems and methods that not onlyenhance the security of block-chain ledger architectures for usehigh-risk, sensitive applications, but that also provide a frameworkthat provides owners or holders of assets tracked by block-chain ledgerarchitectures with recourse in an event of fraud or malicious activity,while maintaining the public availability and verificationcharacteristic of block-chain ledgers.

b. Exemplary Hybrid Public-Private Block-Chain Ledger Architectures

The disclosed embodiments address these and other problems associatedwith conventional block-ledger architectures in a technical manner, byproviding computer-implemented systems and methods that augment aconventional block-chain ledger with a private-master encryption keyarchitecture that, in conjunction with an owner's pair of public andprivate block-chain keys, selectively encrypt ledger data to protectboth a privacy of owners of tracked assets and a confidentiality ofexisting instruction sets maintained within the block-chain ledger.

Further, by incorporating an encrypted rules engine and correspondinglist of triggering events (e.g., an event triggers list) into each blockof the conventional block-chain ledger architecture (and thus generatinga hybrid, public-private block-chain architecture), computer-implementedsystems and methods consistent with the disclosed embodiments mayperform operations that provide owners or holders tracked assets withrecovery options in an event of fraud or malicious activity, whilemaintaining the public availability and verification characteristic ofconventional block-chain ledgers.

In certain aspects, discrete data blocks of the conventional block-chainledgers (e.g., as outlined above in reference to FIG. 2) and of thehybrid block-chain ledgers (e.g., as described in reference to FIG. 3)may include common elements of data that may specify transactions thatdistribute, transfer, and/or otherwise act upon portions of trackedassets. For example, these common data elements may include, but are notlimited to, input data that references one or more prior transactions(e.g., a cryptographic hash of the one or more prior transactions),output data that includes instructions for transferring the trackedasset portion to one or more additional owners (e.g., a quantity ornumber of units of the tracked asset portion that are subject to thetransaction and a public key of the recipient) and further, a digitalsignature applied to the input and/or output data using a correspondingpublic key of a current owner of the tracked asset portion. Thedisclosed embodiments are, however, not limited to exemplarytransactions that include a transfer of tracked assets and to theexemplary data elements described above, and in further embodiments,discrete blocks of the hybrid block-chain ledgers may represent anyadditional or alternate transaction appropriate to the tracked assets,and further, any additional or alternate data appropriate to the trackedassets and to the transaction.

In contrast to the conventional block-chain ledgers described above, thedisclosed embodiments may establish a “centralized authority” whichcontrols the rules engine and the trigger list. The centralizedauthority establishes and maintains rules (e.g., through the rulesengine and corresponding list of triggering events) that facilitateregulatory-based, policy-based, and customer-specified controls oftransactions involving the tracked assets (e.g., units of virtualcurrency, etc.). The triggering event list and the rules engine vets alltransactions. The centralized authority controls the rules engine, andthe trigger list, while the user is able to review and possibly modifythe trigger list using their own private key.

For example, and as described above, business entity 150 may representthe centralized authority, and one or more computing components ofsystem 150 may perform operations that establish the rules engine andthe list of triggering events, which may be stored within a secure datarepository (e.g., data repository 144). In some aspects, the generatedand stored rules engine may identify or more rules that regulate adistribution of the tracked assets, an initiation of one or moretransactions involving the tracked assets (e.g., a sale, a use of thetracked assets as collateral in a secured transaction etc.), andfurther, any additional or alternate action involving the tracked assetsand/or the hybrid public-private ledger (e.g., processes that generateadditional cryptographic key sets for user 110, processes that recoverassets racked in the hybrid public-private ledger, etc.). Further, andas described above, the generated and stored list of triggering eventsmay include information that specifies causal relationships between oneor more of the established rules and one or more events that trigger aninitiation of one or more corresponding regulated distributions,transactions, and/or actions associated with assets tracked within thehybrid public-private ledger (e.g., the triggering events).

In some aspects, system 140 may establish one or more of the rulesand/or triggering events to reflect regulations and/or policiespromulgated by governmental entity, a financial regulator, and/or thecentralized authority. For example, system 140 may establish a loss of aprivate key by user 110 as a “triggering event” that would cause system140 to perform operations that create a new transaction and generate anew pair of public and private block-chain keys for user 110 in responseto a verification of particular authentication credentials. In otheraspects, system 140 may establish one or more of the rules and/ortriggering events based on information received from user 110 (e.g., asinput provided to a web page or other graphical user interface (GUI)presented by client device 104 and provided to system 140). For example,user 110 may specify a particular distribution of tracked assets (e.g.,recurring bill payments, distributions to other owners, etc.) inresponse to an accident involving user 110 and/or user 110's death(e.g., triggering events).

In further contrast to the conventional block-chain ledgers describedabove, one or more computing components of system 140 (e.g., server 142upon execution of stored instructions) may generate additionalcryptographic keys that facilitate the exemplary regulation oftransactions (e.g., distributions, transfers, and/or actions) involvingassets tracked within the hybrid public-private ledger. By way ofexample, system 140 may generate a master cryptographic key with whichsystem 140 may encrypt the generated and stored rules engine. In someaspects, certain aspects, system 140 may store copies of the generatedmaster key in a portion of data repository 144 that is not accessible touser 110 (and any other users), thus maintaining a confidence of thegenerated master key.

System 140 may also perform operations that encrypt the generated listof triggering events, either alone or in conjunction with metadataidentifying the centralized authority and/or information facilitating aprocessing of the transaction blocks throughout the hybrid block-chainledger. In certain aspects, system 140 may also perform operations thatgenerate and maintain additional private cryptographic keys (e.g., aprivate “crypto” key) associated with each owner associated with theassets tracked within the hybrid block-chain ledger (e.g., users 108,110, and/or 112) and further, that would enable the owners to decryptand access the list of triggering events and additionally oralternatively, the metadata identifying the centralized authority.System 140 may store copies of the generated private crypto keys in aportion of data repository 144. Furthermore, system 140 may also performoperations that provide corresponding ones of the private crypto keys tousers 108, 110, and/or 112 through secure, non-accessible and/orout-of-band communications.

The disclosed embodiments may also be configured to communicate theencrypted and/or hashed rules engine and list of triggering events toowners of and/or user associated with the tracked assets through“in-band” communication processes, such as through an incorporation ofthe encrypted rules engine and list of triggering events into thetransaction blocks of the hybrid block-chain ledger. For example, system140 may perform operations that hash the encrypted rules engine and listof triggering events into a genesis block of the hybrid block-chainledger, the contents of which may be incorporated (e.g., by clientdevices 102, 104, and/or 106, peer systems 160, etc.) into each of thesubsequent transaction blocks generated and appended to the hybridblock-chain ledger. In some aspects, by incorporating the hashed andencrypted rules engine and list of triggering events into blocks of thehybrid block-chain ledger, the disclosed embodiments may ensure that theestablished rules are followed even in an event of actions by maliciousparties to disrupt the tracked assets (e.g., instances of Bitcoin™peeling, etc.)

Further, in some instances, the additional private crypto keys held bythe owners and/or users (e.g., stored in corresponding ones of clientdevices 102, 104, and/or 106 and accessible to executable applicationprograms) may enable the owners and/or users to access the encryptedlist of triggering events maintained within the hybrid block-chainledger. The owners and/or user may, through corresponding clientdevices, view the individual events that, when detected by system 140,could cause system 140 to perform operations that recover, authorize,audit, and/or verify the transaction and/or ownership data includedwithin the hybrid block-chain ledger (e.g., associated withcorresponding portions of the tracked assets).

In certain aspects, one or more computing components of system 140 mayperform operations that modify portions of the stored rules and/or listof triggering events, e.g., in response to changes in regulations and/orpolicies, in response to additional owner input, etc. In order to accessand modify the generated rules engine (and/or the list of triggeringevents) maintained within the hybrid block-chain ledger, system 140 mayleverage the stored master cryptographic key to access and modify thehashed and encrypted rules engine. System 140 may, in certain instances,encrypt and re-hash the modified rules engine and submit the encryptedand hashed modified rules engine to one or more of peer systems 160 forinclusion in a block of the hybrid block-chain ledger. For example, theone or more of peer systems 160 may incorporate the hashed and encryptedmodified rules engine into the hybrid block-chain ledger as a specialtransaction (e.g., a “0” value transaction), such that the hybridblock-chain ledger tracks each change within the modified rules engine.

FIG. 3 is a schematic diagram of illustrating an exemplary structure 300of a hybrid, public-private block-chain ledger, which may be generatedthrough the interaction of components of computing environment 100, inaccordance with the disclosed embodiments. For example, as described inreference to FIG. 3, users 108, 110, and 112 may be associated withcorresponding devices (e.g., client devices 102, 104, and 106), whichmay be configured to execute one or more stored software applications(e.g., a wallet application) capable of obtaining a current version of ahybrid block-chain ledger from one or more networked computer systems(e.g., one of peer systems 160 configured to “mine” broadcasttransactions and update ledgers).

Further, in some aspects, and as described above, a system associatedwith a centralized authority (e.g., system 140 associated with businessentity 150) may generate a rules engine that regulate transactionsinvolving the assets tracked by the hybrid block-chain ledger (e.g.,distributions, transfers of ownership, other actions, etc.), andfurther, a list of triggering events that, upon detection by system 140,trigger an initiation of one or more of the distributions, transfers,and/or other actions regulated by the generated rules engine. Inadditional aspects, and as described above, system 140 may generate amaster encryption key (e.g., master key 301 of FIG. 3), which may besystem 140 may maintain in a portion data repository 144, and maygenerate additional private “crypto” keys 302A and 302B, which may beassociated with corresponding ones of users 108 and 110 In some aspects,system 140 may maintain private crypto keys 302A, 302B, and 302C in aportion of data repository 144 and provide private crypto keys 302A,302B, and 302C to users 108, 110, and 112 through secure, out-of-bandcommunications. System 140 may, in additional aspects, encrypt thegenerated rules engine and the generated list of triggering events, andfurther, perform operations that hash the encrypted rules engine andlist of triggering events into a genesis block of the hybrid block-chainledger (e.g., genesis block 304).

In an embodiment, one of the users (e.g., user 108) may own and/orcontrol a portion of the tracked assets. For example, a deviceassociated with user 108 (e.g., client device 102) may execute a storedsoftware application (e.g., a wallet application) capable of obtaining acurrent version of a hybrid block-chain ledger, including genesis block304, from one or more networked computer systems (e.g., one of peersystems 160 configured to “mine” broadcast transactions and updateledgers). In some aspects, the current version of a hybrid block-chainledger may represent a “longest” block-chain ledger than includes amaximum number of discrete “blocks,” which may identify transactionsthat transfer, distribute, etc., portions of tracked assets amongvarious owners, including user 108.

For example, client device 102 may obtain the current hybrid block-chainledger, and may process the hybrid block-chain ledger to determine thata prior owner transferred ownership of a portion of the tracked assetsto user 108 in a corresponding transaction (e.g., transaction 306,schematically illustrated in FIG. 3). As described above, one or more ofpeer systems 160 may have previously data verified, processed, andpacked data associated with transaction 306, which may be into acorresponding block of the conventional block-chain using any of theexemplary techniques described above and/or apparent to one of ordinaryskill in the art.

In some aspects, as illustrated in FIG. 3, data specifying transaction306 may include input data that references one or more priortransactions (e.g., transactions that transferred ownership of thetracked asset portion to the prior owner), and further, output data thatincludes instructions for transferring the tracked asset portion to user108. For example, and as described above, input data consistent with thedisclosed embodiments may include, but is not limited to, acryptographic hash of the one or more prior transactions (e.g., hash306A), and output data consistent with the disclosed embodiments mayinclude, but is not limited to, a quantity or number of units of thetracked asset portion that are subject to transfer in transaction 302and a public key 306B of user 108 (i.e., the recipient of the trackedasset portion transferred in transaction 306). Further, in some aspects,the transaction data may include a digital signature 306C of the priorowner, which may be applied to hash 306A and public key 306B using aprivate key of the prior owner through any of a number of techniquesapparent to one of skill in the art and appropriate to the conventionalblock-chain ledger architecture.

Further, and in contrast to the conventional block-chain ledgerarchitectures described above, transaction 306 may also includeencrypted and/or hashed copies of rules engine 320 and trigger eventlist 322. In certain aspects, a device of the prior owner (e.g., whichmay execute one or more software applications) may access genesis block304 (e.g., from the current version of the hybrid block-chain ledgerobtained from one or more of peer systems 160), may parse genesis block306, and may extract copies of the encrypted and/or hashed rules engine322 and trigger event list 324. The prior owner's device may transmit toone or more of peer systems 160 along with the hash 306A, public key306B, and digital signature 306C for verification, processing (e.g.,additional cryptographic hashing) and inclusion into a new block of thehybrid block-chain ledger.

In an embodiment, user 108 may elect to further transfer that trackedasset portion to an additional user (e.g., user 110). For example, asdescribed above, the one or more software applications executed byclient device 102 may cause client device 102 to perform operations thatgenerate input and output data specifying a new transaction (e.g.,transaction 308 of FIG. 3) that transfers ownership of the tracked assetportion from user 108 to user 110, and further, that transmit thegenerated data to one or more of peer systems 160 for verification,processing (e.g., additional cryptographic hashing) and inclusion into anew block of the hybrid block-chain ledger.

For example, data specifying transaction 308 may include, but is notlimited to, a cryptographic hash 308A of prior transaction 306, aquantity or number of units of the tracked asset portion that aresubject to transfer in transaction 308, and a public key of therecipient (e.g., public key 308B of user 110). Further, in some aspects,the data specifying transaction 308 may include a digital signature 308Cof the user 108, which may be applied to hash 308A and public key 308Busing a private key 308D of user 108 using any of the exemplarytechniques described above. Further, and by way of example, the presenceof user 108's public key within transaction data included within theconventional block-chain ledger may enable various devices and systems(e.g., client devices 102, 104, and/or 106, peer systems 160, etc.) toverify the user 108's digital signature 308D, as applied to dataspecifying transaction 308.

Additionally, and as described above, client device 102 may also parsedata specifying prior transaction 306 (e.g., as obtained from thecurrent version of the hybrid block-chain ledger) and extract encryptedand/or hashed copies of rules engine 322 and trigger event list 324. Incertain aspects, client device 102 may append the encrypted and/orhashed copies of rules engine 322 and trigger event list 324 to the dataspecifying transaction 308 (e.g., cryptographic hash 308A, public key308B, and digital signature 308C), and transmit the data specifyingtransaction 308B to one or more of peer systems 160 for verification,processing (e.g., additional cryptographic hashing) and inclusion into anew block of the hybrid block-chain ledger.

Further, and as described above, private crypto key 302A may enableclient device 102 (e.g., associated with user 108) to access encryptedevent trigger list 322 upon extracted from the hybrid block-chainledger, as described above. In some embodiments, private crypto key 302Amay provide client device 102 with read-only access to the encryptedevent trigger list 322. In some aspects, client device 102 may obtainprivate crypto key 302A from system 140 using secured out-of-bandcommunications, and additionally or alternatively, as input provided byuser 108 through a web page or other graphical user interface (GUI)presented by client device 104.

In an embodiment, ownership of the tracked asset portion may betransferred from user 108 to user 110 upon verification and publicationof the data specifying transaction 308 within a corresponding block ofthe hybrid block-chain ledger by peer systems 160. In furtherembodiments, and as described above, user 110 may elect to furthertransfer that tracked asset portion to yet another user (e.g., user112). For example, as described above, the one or more softwareapplications executed by client device 104 may cause client device 104to perform operations that generate input and output data specifying anew transaction (e.g., transaction 310 of FIG. 3) that transfersownership of the tracked asset portion from user 110 to user 112, andfurther, that transmit the generated data to one or more of peer systems160 for verification, processing (e.g., additional cryptographichashing) and inclusion into a new block of the hybrid block-chainledger.

For example, data specifying transaction 310 may include, but is notlimited to, a cryptographic hash 310A of prior transaction 308, aquantity or number of units of the tracked asset portion that aresubject to transfer in transaction 310, and a public key 310B of user112. Further, in some aspects, the data specifying transaction 310 mayinclude a digital signature 310C of the user 110, which may be appliedto hash 310A and public key 310B using a private key 310D of user 110,as described above. Additionally, and by way of example, the presence ofuser 110's public key 308B within transaction data included within thehybrid block-chain ledger may enable various devices and systems (e.g.,client devices 102, 104, and/or 106, peer systems 160, etc.) to verifythe user 110's digital signature 310C, as applied to data specifyingtransaction 310.

Additionally, and as described above, client device 104 may also parsedata specifying prior transaction 308 (e.g., as obtained from thecurrent version of the hybrid block-chain ledger) and extract encryptedand/or hashed copies of rules engine 322 and trigger event list 324. Incertain aspects, client device 104 may append the encrypted and/orhashed copies of rules engine 322 and trigger event list 324 to the dataspecifying transaction 310 (e.g., cryptographic hash 310A, public key310B, and digital signature 310C), and transmit the data specifyingtransaction 310 to one or more of peer systems 160 for verification,processing (e.g., additional cryptographic hashing) and inclusion into anew block of the hybrid block-chain ledger. In an embodiment, ownershipof the tracked asset portion may be transferred from user 110 to user112 upon verification and publication of the data specifying transaction310 within a corresponding block of the hybrid block-chain ledger bypeer systems 160.

Further, and as described above, private crypto key 302B may enableclient device 104 (e.g., associated with user 110) to decrypt eventtrigger list 322 upon extraction from the hybrid block-chain ledger, asdescribed above. In some aspects, client device 104 may obtain privatecrypto key 302B from system 140 using secured out-of-bandcommunications, and additionally or alternatively, as input provided byuser 110 through a web page or other graphical user interface (GUI)presented by client device 104. In other aspects, client device 104 mayidentify and extract private crypto key 302B from a portion of thehybrid block-chain ledger obtained from peer systems 160 (e.g., as asecure in-band communication).

In the embodiments described above, system 140 may establish andmaintain rules (e.g., through a rules engine and corresponding list oftriggering events) that facilitate regulatory-based, policy-based, andcustomer-specified controls of transactions involving assets trackedwithin a hybrid block-chain ledger. For example, client devices 102,104, and/or 106 may generate transaction data that includes and rulesengine and list of triggering events, and one or more of peer systems160 may embed the generated transaction data into blocks of the hybridblock-chain ledger for reference in subsequent transactions. Further, incertain aspects, system 140 may be configured to detect an occurrence ofan event (e.g., based on data received from client devices 102, 104,and/or 106, etc.), may determine whether the list of triggering eventsincludes the detected event, and when triggering event list includes thedetected event, perform one or more operations consistent with anestablished rule that references the detected event, as described belowin reference to FIG. 4.

FIG. 4 is a flowchart of an exemplary process 400 for automaticallyperforming event-based operations on assets tracked within a hybridblock-chain ledger in accordance with disclosed embodiments. In anembodiment, a centralized authority may be assigned to establishregulatory-based, policy-based, and customer-specified control overassets tracked within the hybrid block-chain ledger. In some aspects,tracked assets consistent with the disclosed embodiments may include,but are not limited to, units of a virtual currency or acrypto-currency, units of financial instruments held by one or moreowners, and physical assets utilized by one or more individuals and/orentities. In some aspects, a computer system associated with thecentralized authority (e.g., system 140 associated with business entity150) may execute one more stored application programs to cause system140 to recover, authorize, audit, and/or verify an ownership of at leasta portion of the tracked assets and/or transactions involving he trackedassets based on established and maintained rules.

In one aspect, one or more computing components of system 140 maygenerate a rules engine and a list of triggering events, which may bestored within a portion of data repository 144 (e.g., in step 402). Forexample, the generated and stored rules engine may identify or morerules that regulate a distribution of the tracked assets, an initiationof one or more transactions involving the tracked assets (e.g., a sale,a use of the tracked assets as collateral in a secured transactionetc.), and further, any additional or alternate action involving thetracked assets and/or the hybrid public-private ledger (e.g., processesthat generate additional cryptographic key sets for user 110, processesthat recover assets tracked in the hybrid public-private ledger, etc.).Further, and as described above, the generated and stored list oftriggering events may include information that specifies causalrelationships between one or more of the established rules and one ormore events that trigger an initiation of one or more correspondingregulated distributions, transfers, and/or actions involving assetstracked within the hybrid public-private ledger (e.g., the triggeringevents).

In certain instances, system 140 may establish, in step 402, one or moreof the rules and/or triggering events to reflect regulations and/orpolicies promulgated by governmental entity, a financial regulator,and/or the centralized authority. For example, system 140 may establisha loss of a private key by user 110 as a “triggering event” that wouldcause system 140 to perform operations that generate a new pair ofpublic and private block-chain keys for user 110 in response to averification of particular authentication credentials. Further, and byway of example, system 140 may deem a documented theft of a portion ofthe tracked assets a “triggering event” that would cause system 140 toperform operations recover the stolen portion of the tracked assets andgenerate a new pair of public and private block-chain keys for user 110.

In other instances, system 140 may establish, in step 402, one or moreof the rules and/or triggering events based on information received fromuser 110 (e.g., as input provided to a web page or other graphical userinterface (GUI) presented by client device 104 and provided to system140). For example, user 110 may specify a particular distribution oftracked assets (e.g., recurring bill payments, etc.) in response to anaccident involving user 110 and/or user 110's death (e.g., triggeringevents). The disclosed embodiments are, however, not limited to theseexemplary triggering events and corresponding rules, and in furtherembodiments, system 140 may establish any additional or alternate rulesand/or triggering events appropriate to the tracked assets, to businessentity 150, and further, to users 108, 110, and 112.

Further, one or more computing components of system 140 may generateadditional cryptographic keys that facilitate the exemplary regulationof transactions (e.g., distributions, transfers, and/or actions)involving assets tracked within the hybrid public-private ledger (e.g.,in step 404). By way of example, in step 404, system 140 may generate amaster cryptographic key with which system 140 may encrypt the generatedand stored rules engine, as described above. In some aspects, certainaspects, system 140 may store copies of the generated master key in aportion of data repository 144 that is not accessible to user 110 (andany other users), thus maintaining a confidence of the generated masterkey.

Further, in step 404, system 140 may also perform operations thatgenerate and maintain additional private cryptographic keys (e.g.,private “crypto” keys) associated with each owner of the assets trackedwithin the hybrid block-chain ledger. As described above, the generatedprivate crypto keys may enable a device of each of owner to decrypt andaccess the list of triggering events and additionally or alternatively,metadata identifying the centralized authority. System 140 may storecopies of the generated private crypto keys in a portion of datarepository 144. Furthermore, system 140 may also perform operations thatprovide corresponding ones of the private crypto keys to users 108, 110,and/or 112 through secure, non-accessible and/or out-of-bandcommunications.

In step 406, system 140 may perform operations that encrypt thegenerated and stored rules engine (e.g., using the master encryptionkey) and further, that encrypt the generated and stored list oftriggering events (e.g., using any of the exemplary techniques describedabove that facilitate decryption using the private crypto keys). Forexample, system 140 may perform operations in step 406 that hash theencrypted rules engine and list of triggering events into a genesisblock of the hybrid block-chain ledger, the contents of which may beincorporated (e.g., by client devices 102, 104, and/or 106, peer systems160, etc.) into each of the subsequent transaction blocks generated andappended to the hybrid block-chain ledger. In some aspects, byincorporating the hashed and encrypted rules engine and list oftriggering events into the blocks of the hybrid block-chain ledger, thedisclosed embodiments may ensure that the established rules are followedeven in an event of actions by malicious parties that disrupt thetracked assets (e.g., instances of Bitcoin™ peeling, etc.).

Further, in some embodiments, one or more computing components of system140 may detect an occurrence of an event involving a portion of thetracked assets, an owner of a portion of the tracked assets, and/or atransaction involving a portion of the detected assets (e.g., in step408). For example, system 140 may receive data from client device 104that indicates user 110 lost a corresponding private block-chain keyassociated with a portion of the tracked assets. In other instances,system 140 may detect an event in step 140 based on data received acrossnetwork 120 from one or more systems associated with local, state,and/or federal governmental entities (e.g., data from a law enforcementsystem notifying business entity 150 of a theft of a portion of thetracked assets, data from a local government confirming a death of anowner of a portion of the tracked assets, etc.). Further, in additionalinstances, system 140 may detect an occurrence of an event based on oneor more sensors and devices communicatively connected to network 120 andcapable of transmitting data to system 140. The disclosed embodimentsare, however, not limited to these exemplary events, and in furtherembodiments, system 140 may be configured to detect any additional oralternate event appropriate to the tracked assets and to the componentsof computing environment 100.

System 140 may also be configured to access the stored list oftriggering events (e.g., within database 144), and may determine whetherthe list of triggering events includes the detected event (e.g., in step410). If system 140 were to identify the detected event within the listof triggering events (e.g., step 410; YES), system 140 may establish thedetected event as a triggering event, and may access the encrypted rulesengine using the master encryption key (e.g., in step 412). System 140may further identify, within the accessed rules engine, one or more ofthe established rules that are causally related to the detectedtriggering event (e.g., in step 414). Further, in some aspects, system140 may be configured to perform one or more operations, eitherindividually or in sequence, that are consistent with the identifiedrules (e.g., in step 416). For example, the accessed rules engine mayinclude information identifying the one or more operations associatedwith the identified rules. In other instances, at least one of theperformed operations may represent a default operation associated withthe identified rules (e.g., a specific type of authentication requiredbefore performing the one or more operations on behalf of user 110).

In one embodiment, one or more computing components of system 140 mayalso determine whether to update portions of the generated rules engineand/or list of triggering events (e.g., in step 418). For example,system 140 may identify an update or modification to one or moreregulations and/or policies promulgated by governmental entity, afinancial regulator, and/or the centralized authority. In otherinstances, system 140 may obtain, from client device 104, informationupdating a rule and/or triggering event previously established by system140 based on input received from user 110 (e.g., through a web pageand/or GUI presented by client device 104).

If system 140 determines to update portions of the generated rulesengine and/or list of triggering events (e.g., step 418; YES), system140 may access appropriate portions of the rules engine and/or list ortriggering events in step 420 (e.g., using the master encryption keyand/or any of the exemplary techniques described above), and may modifythe appropriate portions of the rules engine and/or list of triggeringevents to reflect the updated regulations, policies, user-specifiedrules, and/or user-specified events (e.g., in step 422). In someinstances, system 140 may modify the accessed rules engine by adding anew rule, deleting an existing rule, modifying one or more parameters ofan existing rule, and/or modifying one or more operations associatedwith an existing rule. In other instances, system 140 may modify theaccessed list of event triggers to add a new triggering event, delete anexisting triggering event, and/or add or modify parameters associatedwith an existing triggering event.

In some aspects, system 140 may encrypt and re-hash the modified rulesengine and/or list of triggering events, and may submit the encryptedand hashed modified rules engine and/or list of triggering events to oneor more of peer systems 160 for inclusion in a block of the hybridblock-chain ledger (e.g., in step 424). For example, one or more of peersystems 160 may incorporate the hashed and encrypted modified rulesengine and/or list of triggering events into the hybrid block-chainledger as a special transaction (e.g., a “0” value transaction), suchthat the hybrid block-chain ledger tracks each change within themodified rules engine and/or list of triggering events. Exemplaryprocess 400 is then complete in step 426.

Referring back to step 418, if system 140 were to determine that nomodification to the rules engine and/or the list of triggering events iswarranted (e.g., step 418; NO), exemplary process 400 may pass forwardto step 426, and exemplary process 400 is complete. Further, and inreference to step 410, if system 140 were to determine that the list oftriggering events fails to include the detected event (e.g., step 410;NO), exemplary process 400 may pass forward to step 418, and system 140may determine whether to update portions of the rules engine and/or listof triggering events using any of the exemplary processes describedabove.

In the embodiments described above, and through the generation of themaster cryptographic key and management of the generated rules engineand corresponding list of triggering events, system 140 may performoperations that recover, authorize, audit, and/or verify an ownership ofat least a portion of the tracked assets and/or transactions involvingthe tracked assets. In certain aspects, the operations performed bysystem 140, which utilize hybrid block-chain ledgers consistent with thedisclosed embodiments, would not be possible using the conventionalblock-chain ledgers described above.

For example, user 110 may be an avid user of a virtual orcrypto-currency (e.g., Bitcoin™), user 110 may store a private key(e.g., private key 310D) on a laptop computer (e.g., client device 104)to generate and confirm Bitcoin™ transactions. In one instance, user 110may unfortunately drop the laptop into a swimming pool while confirminga Bitcoin™ with private key 310D, and upon retrieved from the swimmingpool, user 110 may establish that the laptop no longer functions andthat data on the laptop is not recoverable.

Through a device in communication with network 120 (e.g., user 110'ssmartphone), user 110 may access a conventional block-chain ledger, suchas those conventional architectures outlined above, and determine thatthe Bitcoin™ transfer was incomplete when user 110 dropped the laptopinto the swimming pool. Further, user 110 may determine that theBitcoin™ transaction represents an orphaned block within theconventional block-chain ledger, and the Bitcoins™ associated with theorphaned block are unrecoverable and permanently lost.

In other aspects, user 110 may access a hybrid block-chain ledger (e.g.,as described above in reference to FIG. 3), and may determine that theBitcoin™ transfer was incomplete when user 110 dropped the laptop intothe swimming pool. In an embodiment, however, user 110 may provide inputto the smartphone identifying the unrecoverable private key, which thesmartphone may transmit to system 140 across network 120. In someaspects, system 140 may receive the transmitted message (e.g., in step408), may determine that user 110's loss of private key 310D representsa triggering event (e.g., step 410; YES), and may perform operationsthat authenticate user 110's identity and that regenerate a pair ofprivate and public block-chain keys for user 110, which system 140 maytransmit to user 110 through any of the secure non-accessible processesoutlined above (e.g., in steps 412, 414, and 416). Upon receipt of thenewly generated private key, user 110 may access the hybrid block-chainledger (e.g., through the smartphone) and confirm the Bitcoin™ transferto recover the crypto-currency.

Further, and by way of example, user 110 may access a wallet applicationexecuted by client device 104, and further, may determine that themobile wallet is missing a number Bitcoins™. User 110 may suspect thatthe loss of the Bitcoins™ represents a theft by a malicious entity, andthrough a complex search of a corresponding block-chain ledger (e.g.,conventional block-chain ledgers described above, and/or hybridblock-chain ledgers consistent with the disclosed embodiments), user 110may trace the theft of the Bitcoins™ to a single transaction within acorresponding block. User 110 may contact the police e-crime unit andreport the theft, and the police may confirm the accuracy of user 110'sallegations regarding the theft.

User 110 may, in some instances, be capable of processing theconventional block-chain ledgers described above to determine an addressof the malicious entity responsible for the theft. The decentralized andanonymous nature of conventional block-chain ledgers may, however,prevent user 110 from identifying the malicious entity, and the stolenBitcoins™ may remain permanently unrecoverable.

The disclosed embodiments may, however, address the deficiencies ofconventional block-chain ledgers and provide user 110 with recourse torecover the stolen Bitcoins™. For example, the police e-crime unit maynotify the centralized authority of the theft of user 110's Bitcoins™and destination address associated with the malicious entity (e.g.,through a message transmitted to system 140 and received, e.g., in step408). System 140 may determine that the theft of the Bitcoins™represents a triggering event included within the generated list (e.g.,step 410; YES), and may perform operations that automatically create arequest for a new transaction that returns the stolen Bitcoins™ to user110 using any of the exemplary techniques described above (e.g., insteps 412, 414, and 416). System 140 may also perform operations thatregenerate a pair of private and public block-chain keys for user 110,which system 140 may transmit to user 110 through any of the securenon-accessible processes outlined above (e.g., in steps 412, 414, and416).

The hybrid block-chain ledger architectures described above may add alevel of sophistication to conventional mechanisms for trustlesscommunication by allowing transactions involving tracked assets to occuraccording to common transaction rules. Further, the hybrid block-chainledger architectures consistent with the disclosed embodiments may allowowners of the tracked assets to project authority over the trackedassets by establishing customized rules for transaction authorization.Furthermore, and in contrast to the conventional techniques describedabove, the hybrid block-chain ledger architecture may enable acentralized authority (e.g., business entity 150 associated with system140) to recover, audit, and/or verify an ownership of at least a portionof the tracked assets and/or transactions involving the tracked assetsbased on established and maintained rules.

In the embodiments described above, and through the generation of amaster cryptographic key and management of a generated rules engine andcorresponding list of triggering events, system 140, acting as acentralized authority, may perform operations that recover, authorize,audit, and/or verify an ownership of at least a portion of the trackedassets and/or transactions involving the tracked assets. In someaspects, and as outlined above, tracked assets consistent with thedisclosed embodiments may include, but are not limited to, units of avirtual currency or a crypto-currency, units of financial instrumentsheld by one or more owners, and physical assets utilized by one or moreindividuals and/or entities.

In additional aspects, the exemplary hybrid block-chain algorithmsdescribed above may track a location, performance, usage, and/or statusone or more additional client devices (e.g., “connected devices)disposed within computing environment 100 (not shown in FIG. 1), whichmay be configured to establish communications with client devices 102,104, and 106, and further, with system 140, using any of thecommunications protocols outlined above. For example, client device 102,104, and 106, system 140, and the connected devices may be uniquelyidentifiable and addressable within communications network 120, and maybe capable of transmitting and/or receiving data across the establishedcommunications sessions. Further, in some aspects, system 140 may beconfigured to establish the communications sessions with one or more ofthe connected devices, and to exchange data with the connected devicesautonomously and without input or intervention from a user of clientdevice 104 (e.g., user 110).

In some aspects, the connected devices may be implemented as aprocessor-based and or computer-based device that includes one or moreprocessors and tangible, computer-readable memories, as described abovein reference to client devices 102, 104, and 106. By way of example,connected devices consistent with the disclosed embodiments may include,but are not limited to mobile communications devices (e.g., mobiletelephones, smart phones, tablet computers, etc.) and other devicescapable of communicating with client device 104 (e.g., internet-readytelevisions, internet-ready appliances and lighting fixtures, computingdevices disposed within motor vehicles, etc.).

Further, in additional aspects, the connected devices may include sensordevices in communication with the one or more processors and thememories. The sensor devices may, in some aspects, be configured tomonitor the usage, location, status, etc., of corresponding ones of theconnected devices, and may be configured to provide sensor data tocorresponding ones of the processors. In some aspects, the sensor datamay include, but is not limited to, data identifying a current state,data specifying intended and/or unintended interaction with one or moreof users 108, 110, and/or 112 (e.g., through client devices 102, 104,and/or 106), inadvertent interactions (e.g., drops, other accidentalinteractions, etc.), and data describing any additional or alternatecharacteristics of the connected devices capable of being monitored andquantified by the sensor devices.

In other aspects, computing environment 100 may include one or moreadditional computing systems in communication with the connected devicesusing any of the communications protocols outlined above. The additionalcomputing system may, in an embodiments, may include one or more sensordevices capable of monitoring a location, performance, usage, and/orstatus of the connected devices, which may establish a “sensor network”capable of monitoring the connected devices. These additional computingsystems may provide the additional sensor data to the connected devicesusing any of the communications protocols outlined above, either aregular intervals or in response to requests from the connected devices.In some instances, the additional computing systems may be implementedas processor-based and/or computer-based systems consistent with theexemplary systems described above.

In further aspects, the connected devices may be configured to transmitportions of the sensor data (e.g., as detected by on-board sensordevices and/or received from the sensor network) to client devices 102,104, and/or 106 and additionally or alternatively, to system 140, usingany of the communications protocols outlined above. By way of example,the sensor data may characterize and interaction between the connecteddevices and users 108, 110, and 112 (e.g., the monitored data mayrepresent usage data indicative of a consumption of one or more servicesprovided by the connected devices), and the connected devices and maytransmit the usage data for users 108, 110, and/or 112 to correspondingones of client devices 102, 104, and/or 106, which may store thereceived usage data in a corresponding data repository. In furtheraspects, the connected devices may also transmit the usage data tosystem 140, along with information linking specific elements of theusage data to corresponding users and/or client devices (e.g., user110's usage data may be linked to an identifier of user 110 and/or ofclient device 104). In certain aspects, as described below in referenceto FIGS. 4 and 5, client devices 102, 104, and/or 108 may alsoincorporate corresponding portions of the monitored data, e.g., asreceived from the connected devices, into hybrid block-chain ledgersconsistent with the disclosed embodiments in order to record, track, andpublicly monitor the location, performance, usage, and/or status of theconnected devices.

FIG. 5 is a schematic diagram of illustrating an exemplary structure 500of a hybrid, public-private block-chain ledger, which may be generatedthrough the interaction of components of computing environment 100, inaccordance with the disclosed embodiments. For example, as described inreference to FIG. 4, users 108, 110, and 112 may be associated withcorresponding devices (e.g., client devices 102, 104, and 106), whichmay be configured to execute one or more stored software applications(e.g., a wallet application) capable of obtaining a current version of ahybrid block-chain ledger from one or more networked computer systems(e.g., one of peer systems 160 configured to “mine” broadcasttransactions and update ledgers).

In some aspects, and as described above, the embodiments described inFIG. 5 may incorporate the exemplary hybrid block-chain ledger describedabove in reference to FIG. 3 (e.g., hybrid block-chain ledger structure300), and may augment hybrid block-chain ledger structure 300 to includeand track monitored data indicative of a location, performance, usage,and/or status of one or more connected devices 402 disposed withinenvironment 100 and in communication with client devices 102, 104, and106. For example, and as described above, connected devices 502 may beimplemented as processor-based and/or computer-based systems thatinclude one or more processors and corresponding tangible,non-transitory computer-readable memories.

Further, the one or more processors of connected devices 502 may obtainsensor data from one or more on-board sensor devices capable ofmonitoring connected devices 502 and additionally or alternatively, fromone or more external sensor devices disposed within additional computingsystems in communication with connected devices 502. The on-board andexternal sensor devices may, in some aspects, collectively form a sensornetwork 504 that generates and provides sensor data to the connecteddevices. For instance, and as described above, the sensor data mayinclude, but is not limited to, data identifying a current state, dataspecifying intended and/or unintended interaction with one or more ofusers 108, 110, and/or 112 (e.g., through client devices 102, 104,and/or 106), inadvertent interactions (e.g., drops, other accidentalinteractions, etc.), and data describing any additional or alternatecharacteristics of the connected devices capable of being monitored andquantified by the sensor devices. In some aspects, the connected devicesmay be configured to transmit portions of the received sensor data tocorresponding ones of client devices 102, 104, and 106, and to system140, using any of the communications protocols outlined above (e.g.,through peer-to-peer communications, etc.).

For example, the sensor data received by connected devices 502 mayspecify a usage or a consumption of one or more services of theconnected devices by corresponding ones users 108, 110, and 112 (e.g.,associated with client devices 102, 104, and 106). In some aspects,portions of the usage data attributable to corresponding ones of users108, 110, and 112 may be transmitted to corresponding ones of clientdevices 102, 104, and 106, and further, to system 140. In furtheraspects, the user-specific portions of the usage data may be storedwithin corresponding user-specific usage data repositories (e.g., usagedata repositories 506, 508, and/or 510 of FIG. 4). In some embodiments,as described below in reference to FIG. 5, client devices 102, 104,and/or 106, in conjunction with system 140, may augment the exemplaryhybrid block-chain ledger structures described above to include usagedata and corresponding metadata, thus enabling the hybrid block-chainledger to monitor the location, performance, usage, and/or status of theconnected devices over time (e.g., during transfers in ownership of theconnected devices, use of the connected devices as collateral, etc.).

FIG. 6 is a schematic diagram of illustrating an exemplary structure 600of a hybrid, public-private block-chain ledger, which may be generatedthrough the interaction of components of computing environment 100, inaccordance with the disclosed embodiments. For example, as described inreference to FIG. 6, users 108, 110, and 112 may be associated withcorresponding devices (e.g., client devices 102, 104, and 106), whichmay be configured to execute one or more stored software applications(e.g., a wallet application) capable of obtaining a current version of ahybrid block-chain ledger from one or more networked computer systems(e.g., one of peer systems 160 configured to “mine” broadcasttransactions and update ledgers).

In some aspects, and as described above, the embodiments described inFIG. 5 may incorporate the exemplary hybrid block-chain ledger describedabove in reference to FIGS. 3 and 5 (e.g., hybrid block-chain ledgerstructures 300 and 400), and may augment hybrid block-chain ledgerstructure 300 of FIG. 3 to include and track monitored data indicativeof a location, performance, usage, and/or status of one or moreconnected devices 502 disposed within environment 100 and incommunication with client devices 102, 104, and 106, as received fromsensor network 404.

For example, and as described above, a prior user (e.g., user 108) mayelect to further transfer a portion of tracked assets to an additionaluser (e.g., user 110). For example, as described above, the one or moresoftware applications executed by client device 102 may cause clientdevice 102 to perform operations that generate input and output dataspecifying a new transaction (e.g., transaction 308 of FIG. 6) thattransfers ownership of the tracked asset portion from user 108 to user110, and further, that transmit the generated data to one or more ofpeer systems 160 for verification, processing (e.g., additionalcryptographic hashing) and inclusion into a new block of the hybridblock-chain ledger.

For example, data specifying transaction 308 may include, but is notlimited to, a cryptographic hash 308A of a prior transaction (e.g.,which transferred ownership to user 108), a quantity or number of unitsof the tracked asset portion that are subject to transfer in transaction308, and a public key of the recipient (e.g., public key 308B of user110). Further, in some aspects, the data specifying transaction 308 mayinclude a digital signature 308C of the user 108, which may be appliedto hash 308A and public key 308B using a private key 308D of user 108using any of the exemplary techniques described above. As describedabove, the presence of user 108's public key within transaction dataincluded within the conventional block-chain ledger may enable variousdevices and systems (e.g., client devices 102, 104, and/or 106, peersystems 160, etc.) to verify the user 108's digital signature 308D, asapplied to data specifying transaction 308. Further, and as describedabove, client device 104 may also parse data specifying the priortransaction and extract encrypted and/or hashed copies of rules engine322 and trigger event list 324.

Additionally, in some aspects, the data specifying transaction 308 mayalso include user 108's usage data (e.g., as received from connecteddevices 402 using any of the exemplary techniques described above),which may be encrypted using master key 301 (e.g., by array controllerencryption 604B) to generate an encrypted array 604A of user 108's usagedata. In further aspects, the data specifying transaction 308 may alsoinclude metadata indicative of a duration of usage, time, date,location, and/or other network connected devices in proximity, which maybe encrypted using user 108 private crypto key 302A (e.g., by arraycontroller encryption 602A) to generate an encrypted array of metadata602A.

In certain aspects, client device 102 may append the encrypted and/orhashed copies of rules engine 322 and trigger event list 324 to the dataspecifying transaction 308 (e.g., cryptographic hash 308A, public key308B, and digital signature 308C) and the usage data (e.g., encryptedarrays 602A and 604A and array controller encryption 602B and 604B), andtransmit the data specifying transaction 308 to one or more of peersystems 160 for verification, processing (e.g., additional cryptographichashing) and inclusion into a new block of the hybrid block-chainledger.

In further embodiments, and as described above, user 110 may elect tofurther transfer that tracked asset portion to yet another user (e.g.,user 112). For example, as described above, the one or more softwareapplications executed by client device 104 may cause client device 104to perform operations that generate input and output data specifying anew transaction (e.g., transaction 310 of FIG. 6) that transfersownership of the tracked asset portion from user 110 to user 112, andfurther, that transmit the generated data to one or more of peer systems160 for verification, processing (e.g., additional cryptographichashing) and inclusion into a new block of the hybrid block-chainledger.

For example, data specifying transaction 310 may include, but is notlimited to, a cryptographic hash 310A of prior transaction 308, aquantity or number of units of the tracked asset portion that aresubject to transfer in transaction 310, and a public key 310B of user112. Further, in some aspects, the data specifying transaction 310 mayinclude a digital signature 310C of the user 110, which may be appliedto hash 310A and public key 310B using a private key 310D of user 110,as described above. Additionally, and by way of example, the presence ofuser 110's public key 308B within transaction data included within thehybrid block-chain ledger may enable various devices and systems (e.g.,client devices 102, 104, and/or 106, peer systems 160, etc.) to verifythe user 110's digital signature 310C, as applied to data specifyingtransaction 310.

Further, and as described above, data specifying transaction 310 mayalso include user 110's usage data (e.g., as received from connecteddevices 402 using any of the exemplary techniques described above),which may be encrypted using master key 301 (e.g., by array controllerencryption 614B) to generate an encrypted array 614A of user 108's usagedata. In further aspects, the data specifying transaction 308 may alsoinclude metadata indicative of a duration of usage, time, date,location, and/or other network connected devices in proximity, which maybe encrypted using user 110's private crypto key 302A (e.g., by arraycontroller encryption 612B) to generate an encrypted array of metadata612A.

In certain aspects, client device 104 may append the encrypted and/orhashed copies of rules engine 322 and trigger event list 324 to the dataspecifying transaction 310 (e.g., cryptographic hash 310A, public key310B, and digital signature 310C) and the usage data (e.g., encryptedarrays 612A and 614A and array controller encryption 612B and 614B), andtransmit the data specifying transaction 310 to one or more of peersystems 160 for verification, processing (e.g., additional cryptographichashing) and inclusion into a new block of the hybrid block-chainledger.

In certain embodiments, as described above, the inclusion of usage datawithin hybrid block-chain ledgers maintains an continuous log of usageand/or consumption of connected-device resources by users 108, 110, and112, and any additional or alternate users that generate and submit(through corresponding client devices) transaction data to one or moreof peer systems 160. In further aspects, the sensor data (e.g., asreceived from connected devices 402) may be batched in a periodic setand treated as a transaction, and additionally or alternatively, may beappended into an associated repository of the transaction block-chain(e.g., using system 140, peer systems 160, etc.).

Further, in some aspects, the exemplary block-chain ledgers describedabove may facilitate processes that track an ownership of one or more ofthe connected devices and further, enable current owners (e.g., user110) to transfer ownership to others (e.g., user 112). For example, whenthe disclosed embodiments create a new block to account for usage data,a private key of the current owner may be user to authenticate the usageand allow for the generation of the new block. In other aspects, aprivate key linked to a device of the current owner (e.g., storedlocally on a memory of the current owner's device) may authenticate theusage and allow for the generation of the new block without input orintervention from the current owner. In some instances, the private keyof the current owner's device may differ from the current owner'sprivate key, Further, and in some embodiments, the automated andprogrammatic authentication of the usage by the current owner's devicemay reduce instances of under-reported usage data associated withowner-initiated authentication protocols.

III. Exemplary Use Cases for Hybrid Private-Public Ledgers

a. Behavior Tracking Using Connected Devices

In other aspects, the disclosed embodiments may enable a business entity150 (e.g., a financial institution) to track users' behavior and theirability to “care for” and/or “keep in good maintenance” one or moreowned items (e.g., connected devices, such as cars, clothing, andappliances) and/or one or more financial obligations (e.g., timelymonthly mortgage payments, timely payments of credit card bills, nooverdrafts, etc.). For example, business entity 150 may, through system140, monitor and collect user 110's historical behavior data in order todetermine a “care score,” which may factor into a credit adjudicationprocess for user 110. For example, when system 140 accesses ablock-chain repository to determine user 110's “care score,”, system 140may decrypt the current version of the hybrid block-chain ledger usingthe master key, and determine a score for either a specific category ofproducts or an overall score based on the sensor data. System 140 mayestablish the “care rating” for user 110 based on the determined score.Further, the disclosed embodiments may maintain a record ofcorresponding usage data (e.g., within the disclosed exemplary hybridblock-chain ledgers) and adjust a deprecation value, which system 140may store along with a unique identifier value as a key value pair.

The disclosed embodiments may also facilitate processes that groupsubsets of connected devices (e.g., various office equipment), track ausage of these connected devices as a group, and an aggregate theabove-described calculations for the group of connected devices. In someaspects, the tracking and manipulation of group usage data may balanceout the heavy use of a singular item with items which are usedinfrequently.

Further, in some aspects, each of connected devices 402 may provide dataindicative of usage, care, maintenance, and repayments to a centralizedserver (e.g., a server of system 140), which may perform operations thatupdate a creditworthiness of an owner based on the predicted life ofconnected devices 402 and risk exposures (e.g., for purposes ofproviding insurance) in real time. The disclosed embodiments may, forexample, reward good behavior from an individual with rewards of betterterms and/or penalize poor behavior, and thus customizing both load andinsurance product to the individual.

For instance, and consistent with the disclosed embodiments, officeequipment and company car of a business owner may represent “connecteddevices,” and the disclosed embodiments may monitor usage of theconnected devices based on embedded sensors and/or a surrounding networkof sensors disposed within in the environment. In some aspects, portionsof the office equipment may be used infrequently (e.g., as most of thebusiness is off premises), and system 140 may establish, based on theusage data, that the office equipment experiences a relatively low levelof depreciation, while the company car experiences a substantial amountof depreciation. Consistent with the disclosed embodiments, system 140may assign a “medium” deprecation rating to the collective group ofconnected devices (e.g., the office equipment and the company car) basedon the usage data, and system 140 may leverage this information when thebusiness owner attempts to collateralize these connected devices, e.g.,in support of a loan application.

b. Ownership Tracking of Connected Devices and Payment

Additionally, conventional block-chain ledgers are often inadequate totrack a partial ownership of various assets, as ownership rights andagreements change over the course of time. Moreover, actual cosigners ofloans or accounts may experience difficulty in establishing their ownindividual responsibility in the instances of partially owned assets.

Hybrid block-chain ledgers consistent with the disclosed embodimentsmay, in some aspects, provide a shared ledger payment mechanism that, atthe time of purchase settlement, assigns ownership to a purchased itemby making a connection to the item and embedding the item with an uniqueowner identifier, timestamp and purchase value. If there were splitownership of the item, the disclosed embodiments may record the multipleowners as a value pair and register corresponding percentages ofownership. The disclosed embodiments may further complete registrationof the purchased item within the hybrid block-chain ledger, which tracksthe ownership and allows the system and/or devices of devicesperiodically check-in with the ledger system to maintain a correspondingownership record.

By tracking partial ownership of assets, hybrid block-chain ledgersconsistent with the disclosed embodiments may allow for real-timetracking of individual contributions spread over the entire ownershipstructure. In certain aspects, the real-time tracking provided by thedisclosed embodiments may be useful in partial ownership situations withcomplex disbursement schemes. For example, using any of the exemplarytechniques described above, system 140 may perform operations thatautomatically disburse profits according to the ownership and/ordisbursement arrangements and/or create new genesis blocks based on theownership instructions set forth within event trigger list 322 and/orrules engine 324.

For instances, a husband and wife may jointly purchase car for $10,000.Upon the completion of payment for the car, system 140 may determinethat husband contributed 60% of the cost, and the wife contributed 40%of the cost. In some aspects, rules engine 324 may include rulesestablishing joint ownership on the basis of the proportionalcontributions of the husband and wife, and in the event of divorce(e.g., a triggering event within event trigger list 322), system 140 maydistribute the ownership in accordance with rules engine 324. Thedisclosed embodiments are, however, not limited to property settlementssubsequent to divorce, and event trigger list 322 and/or rules engine324 may include additional data that supports the disbursement ofprofits upon sales of items and/or within a partnership.

Further, a startup company may exhibit a distributed ownership structureincluding three co-founders and an investor owner. In certain aspects,rules engine 324 may include an existing payment structure rule thatspecifies a distribution of profits among the co-founders and theinvestor. When the startup company is acquired or receives funding,system 140 may detect a triggering event, and rules engine 322 proceedsto create a new ownership structure, and creating a new genesis block.

c. Automated Ownership Transfers

Using conventional block-chain ledger systems, all entries are madesequentially and are generated in a wide range of applications, whichcan lead to delays in executing the transactions. Many transactions,however, follow a standardize set of rules based on events associatedwith the owner. In some aspects, the disclosed hybrid block-chainledgers may facilitate a transfer of ownership of tracked assets inresponse to an occurrence of a set of standardize events, thusexpediting disbursement and ownership transfers, and reducing the needfor protracted analysis of the ownership structures.

The disclosed embodiments may, for example, track an ownership ofconnected devices based on a unique identifier and periodic checks witha network connection, which may be aggregated with associated data(e.g., value, purchase time, usage duration, geo-location, etc.) to forma connected asset inventory system. If items cannot periodically checkinto the ownership network, system 140 may prompt the customer will beprompted to reconcile, or a public network may request independentverification.

The disclosed embodiments may also establish a number of predeterminedtrigger conditions which, when triggered, execute the sale ordisbursement and re-allocation of ownership of items registered with theconnected asset inventory system. These predetermined instructions maybe stored on a ledger system, and the event and completion of thedisbursement may be validated by the pubic “miners” (e.g., pee systems160).

In some aspects, transactions related to ownership of a particularproperty may be added to the exemplary hybrid block-chain ledgersdescribed above. System 140, acting on behalf of the centralizedauthority (i.e., business entity 150) may generate a genesis block inpartnership with a manufacturer/retailer at the time of purchase, and/orappends information from a genesis block created by a manufacturer.System 140 may also generate a set of rules for ownership transfer basedon input from the individuals involved in the transfer, which may beincorporated into the hybrid block chain ledger as a rules engine (e.g.,rules engine 322) using any of the exemplary techniques described above.Public portions of hybrid block-chain ledgers consistent with thedisclosed embodiments may verify a current status of ownership, and whena preset event or criteria is reached (e.g., within event trigger list322), system 140 performs operations that initiate a transfer ofownership of the property based on the established rules, and theownership transfer is updated through the distributed network.

For instances, life insurance claims processes may proceed upon a deathof a family member and a receipt of an official “certified” deathcertificate from a governmental entity (e.g., trigger events). Thedisclosed embodiments may, in some aspects, require that the ledger“miners” of peer systems 160 validate the trigger events as well asvalidate the completion of the “disbursement” or payment event.

Further during estate planning, the disclosed embodiments may “tag” ortrack every asset that uses a network connection to generate and createrules around automatic disbursements. Upon an event trigger/confirmation(e.g., as specified in event trigger list 322), system 140 automaticallyputs into effects the rules created by a customer (e.g., as storedwithin rules engine 324). The automated transfer of ownership may, insome aspects, reduce the workload of an executor and track all changesmade to the event triggers, which allows for greater clarity.

d. Processes for Tracking Earmarked Distributions

In certain aspects, many electronic funds transfers are earmarked forspecific uses and/or for specific purchases of certain types of products(e.g., earmarked donations, child support, welfare, kid's allowance,some government grants, etc.). Using conventional processes, it may bedifficult to track and verify that the allotted funds are used strictlyon allowed purchases. Furthermore, using conventional processes, anindividual that provides funds may rely on reports the individualspending the funds the earmark has been respected, and moreover, theappropriate use of funds may often be taken on faith.

The disclosed embodiments may enable a hybrid block-chain ledger tocreate and enforce rules controlling transfer of earmarked funds, thusproviding a systematic mechanism for tracking and controlling spending.For example, system 140 may establish (e.g., in rules engine 322) a setof allowed transaction rules that enforce the set of earmarks forparticular funds.

In some aspects, these systems could be used in internationalremittance, where funds are sent for specific uses. If the transactionis earmarked for specific items and/or types of items, the establishedrules may be incorporated into an encrypted event trigger list and/orrules engine (e.g., by system 140) within the transaction block sendingthe funds overseas, as described adobe. The recipient of the fund willbe able to review the trigger events that facilitate a use of theparticular funds, and if they attempt to use the funds in a way thatviolates the transaction earmarks, the transaction could be refused,and/or the provider of the fund could be notified.

In some aspects, system 140 may establish rules within the rules engine(e.g., rules engine 324) that allow compliant transactions to proceed,while initiating a set of contingency steps transactions outside of theearmarks. These steps may, but are not limited to, include notificationof the originating party, flagging the transaction, denying thetransaction to name a few.

For example, a customer of business entity 150 (e.g., user 110) mayintend to send money to his parents to repair their roof in a remotevillage in China. User 110's parents do not have a bank account, so user110 must send the money through an intermediary (e.g., user 112). User110 may worry that user 112 may use the funds inappropriately, leadingto an unrepaired roof. In some aspects, user 110 may transfer fundsusing the exemplary hybrid block-chain described above, and mayestablish (e.g., within event trigger list 322 and/or rules engine 324)an earmark for s contractor already selected for the roof repairs.Although user 112 believes she can get a better deal by getting the roofrepaired by a different contractor, user 112 access event trigger list322 (e.g., using user 112's private crypto key) and determines that thedifferent contractor cannot be paid with user 110's funds.

e. Shipping Beacons Based on Connected Devices

The consumer market may be moving towards a model where purchases aremade directly from manufacturers. In some instances, as the point ofpurchase becomes closer and closer to the manufacturers, inherentproblems exist in tracking and paying for these goods in an equitableway that protects both the manufacturer and the purchaser. For example,using conventional processes, a cost of a product is paid up-front by apurchaser, who relies on the seller's reputation and ethical behavior toproduce and ship the product. As smaller manufacturers enter the marketplace and purchases are made on a global scale, these conventionalpayment processes are often unable to account for the realities ofmodern consumer and manufacturer behavior.

Using the disclosed embodiments, the exemplary hybrid block-chainledgers described above may for a basis for a payment system that tracksthe good/product through its shipping route, thus mitigating risksassociated with remote purchases, and incentivizing manufacturer toproduce and ship their products on schedule. For example, upon thepurchase of good from a manufacturer, system 140 may establish a paymentand shipment schedule, which may be included within event trigger list322 and/or rules engine 324. Further, upon acceptance of the conditionsby the manufacturer, and system 140 may disburse an initial amount offunds to the manufacturer and create an appropriate genesis/new blockusing any of the exemplary techniques described above.

A trusted shipping party (e.g., FedEx™, DHL™, etc.) may utilize aprivate key to sign transactions along one or more stages of shipping ofthe product, and a partial disbursement of funds may occur at thesestages to both the trusted shipping party and the manufacturer. As theshipment crosses set target checkpoints (e.g., International borders,customs, provincial/state boundaries, etc.) further partial disbursementis made as the trust shipping party signs transactions within the hybridblock-chain ledger. When the purchaser signs the receipt of the productinto the hybrid block-chain ledger, system 140 may perform operations tomake the final disbursement, thus settling all accounts of the shipment.

For example, a customer of business entity 150 (e.g., user 110) maypurchase ten barbecues from an overseas manufacturer for use anddistribution to friends and family. User 110 may approach businessentity 150 and request establishment of a disbursement schedule for themanufacturer based on the exemplary hybrid block-chain ledgers describedabove. System 140 may, in some aspects, create a transaction in thehybrid block-chain ledger that holds user 110's payment (e.g., an escrowaccount), and system 140 may establish rules that sequentially disbursethe payment when the item ship, when the items clear customs, when theyare in the same town as user 110, and finally when user 110 is able tosign for items after inspection.

f. Clearinghouse Models for Contract Settlement

In some instances, “smart contracts” that leverage conventionalblock-chain ledgers may serve to enforce agreements in a timely andefficient manner creating a permanent record of the transaction with allthe enforceable rules associated with the contracts. In further aspects,the use of the exemplary hybrid block-chain ledgers described aboveallows the terms of these smart contracts to be modified by acentralized authority to accommodate the changing realities of the realworld. Problems remain, however, surrounding the reconciliation ofdisputes and/or the initiation of transactions by the centralizedauthority to correct problems in the list of transactions.

In some aspects, the exemplary hybrid block-chain ledgers describedabove may be further augmented to include a “side” block-chain ledgerthat tracks any automated transactions initiated either by the rulesresiding on the hybrid block-chain ledger (e.g., event trigger list 322and/or rules engine 324) or by a centralized authority having power toenact a transaction outside of normal transaction usage.

When a rule-based or centralized-authority-initiated transaction occurs,the associated supporting documentation and triggering events may betracked in a special transaction category that requires validation byneutral third party to verify that the transaction is in-line with theset of rules/agreements allowed on those particular smart contracts.These processes allow for reconciliation of assets, funds, and ledgertracked items via a neutral third party. The disclosed embodiments mayalso allow for parties involved in the transaction to request reviews oftransactions in cases of errors or conflicting triggering events, and aneutral third party may act as an arbitrator in the cases where conflictexists.

For example, the disclosed embodiments may enable a customer of businessentity 150 (e.g., user 110) to create, within a hybrid block-chainledger, a contractor renovating user 110's house. The smart contractmay, in some aspects, specify scheduled disbursements based on mutuallyagreed-upon inspections of work. In one instance, the contractorpresents and inspection report to a corresponding financial institutionto receive a scheduled disbursement. Upon receipt of a notification ofthe disbursement, user 110 requests that system 140 recovers thedisbursement, and user 110 has not completed the requisite andtriggering inspection, and system 140 generates non-compliance rules(e.g., within rules engine 324 using the master key or within the sideblock-chain) to recover user 110's funds. The contractor may, however,argue to the financial institution that the required inspection hasoccurred and provides a corresponding report (that was not signed off byuser 110's private key). Business entity 150 and the contractor'sfinancial institution may initiate an automated arbitration between user110 and the contractor against the terms of the smart contract. Thearbitration finds in favor of user 110, who recovers the funds, andsystem 140 records the arbitration decision into correspondingtransaction data for submission to peer systems 160, as described above.

g. Document Tracking Using Hybrid Block-Chain Ledgers

In further instances, processes that maintain deeds and other importantdocument are crucial for proper record keeping and accessibility. Thedisclosed embodiments may be configured to the records are maintained ina secure, accessible repository and available to prove ownership or anoccurrence of an event in a case of conflicting documentation. Forexample, the disclosed embodiments may hash a document into theexemplary hybrid block-chain ledgers described above using a secure,known pixel replacement to add further encryption. The hashed documentmay also be used in the case of transactions, and an ownership chain maybe maintained. Further, using the hybrid block-chain ledgers describedabove may enable financial institutions and other entities that provideloans secured against any of these deeds to automatically execute liensin the case of default on the loan. Further, the use of secured imagesmay also provide further security, especially in a case of conflictingdocumentation.

h. Counterfeit Prevention

Processes that prevent an introduction of counterfeit manufactured goodsinto the marketplace are essential to preserve the intellectual propertyrights of manufacturers and ensure that criminal activities do notnegatively affect legitimate manufacturers. In many instances, however,manufacturers lose track of their goods once they leave theirmanufacturing plant and move into the hands of shipping partners ordistribution partners, leaving the possibility that losses may occurbefore a customer is able to purchase the product. The disclosedembodiments may provide a mechanism to track a legitimate productthrough its lifecycle and control and confirm transactions involving thelegitimate product, thus reducing an ability of counterfeiters to enterand disrupt the marketplace.

For example, the exemplary hybrid block-chain ledgers described abovemay function as a public repository of products that tracks ownershipchains. The exemplary hybrid block-chain ledgers described above mayalso provide a centralized authority functionality that enablesmanufacturers to establish rules around transaction (e.g., minimumpricing, authorized dealer location, etc.). The centralized authorityfunctionality may also be shared with a financial institution (e.g.,business entity 150) to control financing terms or transaction funds.

Further, while conventional block-chain ledgers may enable an individualto verify if the product has an authentic chain of custody,manufacturers would have very little control over the distributionchannels and how their products are traded. Through the disclosedembodiments, these same manufacturers would have the ability to identifygoods not offered for sale, or set targeted minimum pricing for certaingeographies to address “grey-market activities” associated with theseproducts.

For instances, a customer of business entity 150 may be a manufacturerand direct sale merchant of a specialized biomedical product with strictexport regulations and a targeted regional sale strategy. The customermay work with business entity 150 to incorporate regional sales rulesinto a hybrid block-chain ledger for each product during manufacturing(e.g., within event trigger list 322 and rules engine 324). Due toimport restrictions one of the rules may specify a location of sales foreach product, and a manufacturer may receive an automated messageindicating that a product intended for a developing market is beingtransacted in the Europe. Working with business entity 150 and localauthorities, the financial transaction is flagged, and the productrecovered due to usage agreement violations. In some aspects, system 140may perform operations that revert an immediately prior transaction backto the customer to facilitate the recovery of their products for properdeployments.

i. Value Tracking Using Block-Chain Ledgers to Capture CustomerInteractions

Today, a deep understanding of the relationship between a customer and abusiness is paramount in delivering a legendary customer experience.Unfortunately, the fragmented nature of existing corporate structurespresents a complex challenge in trying to accurately capture the varioustouch points experienced by a customer. This is especially true of largecorporate entities such as financial institutions, which offers a wideportfolio of products which may operate as separate lines-of-businesses(LOBs) under the same corporate banner. The fragmented nation of theseexisting corporate structures can thus lead to multiple approaches inproviding customer service. The lack of cross-LOB integration may leadto an environment with very low cohesive customer management, which mayalso lead to an inability to track and quantify cross-LOB referrals andinteractions. The disclosed embodiments may provide mechanisms fortracking customer interactions across different LOB's that provide notonly a customer-centric view, but also with techniques for tracking theintrinsic value of each interaction with the customer.

In some aspects, the exemplary hybrid block-chain ledgers describedabove may be configured to track and reward referral programs for asingle customer in a multi-LOB environment. Within a hybrid block-chainledger, the interactions and activities between a customer and staff canbe recorded as a transaction, and the value generated by the transactioncan be added to the hybrid block-chain ledger and compared the expectedvalue of the referral. Effectively tracking the value of eachinteraction and referrals should allow greater visibility andtransparency of the value generation chain. This increased transparencycan be used to optimize the incentives for all participants.

Systems and processes consistent with the disclosed embodiments may, insome aspects, integrate all communication channels into a singletracking system, and provides a platform upon which referrals can bemonetized. These exemplary systems and processes can further increasethe value proposition for each customer going through this interaction.Thus, disclosed embodiments this exhibit advantages over existingsystems which leverage conventional block-chain ledgers.

The exemplary hybrid block-chain ledgers described above can further beaugmented by allowing for incentives and payouts to occur in thetransaction allowing for direct justification of the payouts. Theaugmentation would reduce the need to maintain records of alltransaction, referrals and sales as it would be integrated into a singlelocation in the hybrid block-chain ledgers.

In the hybrid block-chain model described above, the rules surroundinghow incentives and payouts are made can be controlled by a centralauthority, thereby automating the referral processes (e.g., in eventtrigger list 322 and/or rules engine 324). The participants should beable to view the triggers which can translate to the actions, orthresholds associated with the incentives. But the actual distributioncan be controlled by the rules engine hashed within in the exemplaryhybrid block-chain ledger.

In some aspects, system 140 may combine multiple trigger events (e.g.,within even trigger list 322) to invoke the rules engine (e.g., rulesengine 324), which may change the set rewards and incentives. Themultiple trigger events may include, but are not limited to, a certaintransaction value, sale, customer interaction, a referral, and/or acombination thereof.
